Note: these documents may be out of date. For Perl 6 documentation see docs.perl6.org; for specs, see the official test suite.

I'm going to have to point out that docs.perl6.org is not always correct either, and let the significance of the last phrase sink in. The test suite is constantly tweaked to match the behavior of the latest perl6 code, so effectively the only specification for Perl6 is perl6 (caps intentional).
